BS EN ISO 13365-1:2020 Leather Standard

Discover the essential standard for the chemical determination of preservative content in leather with the BS EN ISO 13365-1:2020. This comprehensive document provides a detailed methodology for analyzing the presence of specific preservatives in leather using the advanced technique of liquid chromatography with acetonitrile extraction.

Overview

The leather industry is a cornerstone of fashion, upholstery, and various other sectors, where the quality and safety of leather products are paramount. Preservatives such as TCMTB, PCMC, OPP, and OIT are commonly used to protect leather from microbial degradation. However, their presence and concentration need to be carefully monitored to ensure compliance with safety standards and regulations.

Why This Standard is Important

The BS EN ISO 13365-1:2020 standard is crucial for manufacturers, quality control laboratories, and regulatory bodies involved in the leather industry. It provides a scientifically validated method for determining the concentration of preservatives, ensuring that leather products are safe for consumers and meet international quality standards.

Preservatives Covered

This standard focuses on the following preservatives:

• TCMTB (2-(Thiocyanomethylthio)benzothiazole): A widely used fungicide in leather processing.
• PCMC (p-Chloro-m-cresol): An antimicrobial agent used to prevent mold and bacterial growth.
• OPP (o-Phenylphenol): A fungicide and bactericide used in leather preservation.
• OIT (2-Octyl-2H-isothiazol-3-one): A biocide used to protect leather from microbial attack.

Methodology

The standard outlines a precise method using liquid chromatography with acetonitrile extraction. This technique is renowned for its accuracy and reliability in quantifying chemical substances within complex matrices like leather. The method involves:

1. Sample preparation and extraction using acetonitrile.
2. Separation and identification of preservatives using liquid chromatography.
3. Quantification of each preservative to ensure compliance with safety standards.

BS EN ISO 13365-1:2020

This standard BS EN ISO 13365-1:2020 Leather. Chemical determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography is classified in these ICS categories:

• 59.140.30 Leather and furs

This document specifies a test method by acetonitrile solvent extraction for the determination of the total content (solvent extractible) of the following preservative agents in leather by liquid chromatography:

1. 2-(thiocyanomethylthio)-benzothiazole (TCMTB);

2. 4-chloro-3-methylphenol (PCMC);

3. 2-phenylphenol (OPP);

4. 2-octylisothiazol-3(2H)-one (OIT);

This method can also be used to determine breakdown products of these preservative agents, which protect leather from microbiological attack.
